According to the Daily Star, the Love Island host, 37, is having fun exchanging texts with Mike, 24, - despite The Sun exclusively reporting this week that their flirty friendship is unlikely to ever lead to any romance.

An insider told the newspaper that things are "hotting up" between Caroline and Mike but, at the same time, she isn't taking their flirtation too seriously given Mike's been open about wanting to date around.

"Things are hotting up," said the source.

"They are texting and have a genuine connection but Caroline's not stupid - she knows he's loving life and girls since leaving the villa.

"But things could progress further once the Love Island madness calms down."

It comes as fans noticed Caroline had been 'liking' several of Mike's Instagram posts since he left the villa.

Among the snaps she 'liked' were an image of Mike with fellow islander Chris Hughes at the Love Island reunion party, and two solo shots of Mike striking a smouldering pose.
